SAFETY NOTES

1. Before any other connection is made, the protective earth terminal shall be connected to a protective con-ductor. The Mains (supply voltage) wiring must be terminated in such a way that, should it slip in the cableclamp, the Earth wire would be the last wire to become disconnected.

2. In the case of portable equipment, the protective earth terminal must remain connected (even if the recorder isisolated from the mains supply), if any of the I/O circuits are connected to hazardous voltages*.

WARNING!Any interruption of the protective conductor inside or outside the apparatus, or disconnection of the protectiveearth terminal is likely to make the apparatus dangerous under some fault conditions. Intentional interruption isprohibited.

Note: In order to comply with the requirements of safety standard BS EN61010, the recorder shall have oneof the following as a disconnecting device, fitted within easy reach of the operator, and labelled as thedisconnecting device.a. A switch or circuit breaker which complies with the requirements of IEC947-1 and IEC947-3b. A separable coupler which can be disconnected without the use of a toolc. A separable plug, without a locking device, to mate with a socket outlet in the building

3. The mains supply fuse within the power supply unit is not replaceable. If it is suspected that the fuse is faulty, themanufacturer's local service centre should be contacted for advice.

4. Batteries within recorders are not user replaceable. Contact the manufacturer's local service centre if a problem issuspected.

5. Whenever it is likely that protection has been impaired, the unit shall be made inoperative and secured againstunintended operation. The nearest manufacturer's service centre should be consulted for advice.

6. Any adjustment, maintenance and repair of the opened apparatus under voltage, should be avoided as far as possi-ble and, if inevitable, shall be carried out only by a skilled person who is aware of the hazard involved.

7. Where conductive pollution (e.g. condensation, carbon dust) is likely, adequate air conditioning/filtering/sealingetc. must be installed in the recorder enclosure.

8. Signal and supply voltage wiring should be kept separate from one another. Where this is impractical, shieldedcables should be used for the signal wiring.

9. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipmentmight be impaired.

* A full definition of "Hazardous' voltages appears under 'Hazardous Live' in BS EN61010. Briefly, under normaloperating conditions, hazardous voltages are defined as > 30V RMS (42.2V peak) or > 60V dc.

100 MM RECORDER USER GUIDE

100 mm. RECORDER USER GUIDE

1 INTRODUCTION

The main part of this manual describes recorders fitted with membrane switches on each side of the display unit. An-nex A contains information on older models, (those with status levels prior to L19 (Multi-point recorders) or L22(Continuous-trace recorders)). The status level appears as the last two or three character section of the recorder serialnumber.

The recorder comes in two versions - a continuous-trace recorder with up to four pens and a multipoint recorder giv-ing up to six traces on the chart. Chart annotation is standard with the multipoint version, but is an optional extra(specified at time of order) with the continuous trace recorder. Annotating recorders print power-on and alarm on/offmessages, time and date. Scales and channel tags are also printed on the chart to simplify trace interpretation.

Designed to fit a DIN cutout (138 x 138 mm) the recorders feature an exceptionally small back of panel dimension of220 mm. (no terminal cover) or 236 mm (with cover).

ANNOTATOR BATTERIES

When the batteries associated with the recorders are fully charged, they will maintain the real-time clock for approxi-mately one month (depending on temperature etc.), without power applied to the recorder. The batteries areuncharged when despatched from the factory, and it takes approximately 175 hrs to charge them fully. Should powerbe removed from the recorder before this, the retention time will be reduced accordingly.

1.1 Unpacking the recorder

The recorder is despatched in a special pack designed to give adequate protection during transit. Should the outer boxshow signs of damage, it should be opened immediately and the recorder examined. If there is evidence of damage,the instrument should not be operated and the local representative contacted for instructions. After the recorder hasbeen removed from its packing, the packing should be examined to ensure that all accessories and documentationhave been removed. Once the recorder has been installed, any internal packing should be removed, and stored withthe external packing, against future transport requirements.

2 INSTALLATION

2.1 MECHANICAL INSTALLATION

Figure 2.1 gives installation details.

The recorder is inserted through the panel aperture from the front of the panel. With the weight of the recorder sup-ported, the panel clamps are inserted into one pair of the rectangular apertures (either at the top and bottom or at theright and left sides) of the recorder. The jacking screws are then be tightened sufficiently to clamp the recorder intoposition. EXCESS FORCE SHOULD NOT BE USED IN TIGHTENING THESE SCREWS.

2.2 ELECTRICAL INSTALLATION

Warning!Refer to the safety notes on page 2 of this manual before proceding.

Figure 2.2 gives mains (line) and signal wiring information.

Notes:1. Care should be taken to avoid pen/cartridge contact with

skin or clothing2. The password is set to 010 at the factory but can be edited

in Instrument Configuration.

Before changing the pens/print cartridge, the pens should beparked (fanned) as follows (ref. figure 2.3).

1. From the background display, operate the 'Enter' key.2. Scroll-in the password, then operate 'Enter' twice.

The chart stops and the pens fan, or the printhead moves tothe centre of its travel; the 'H' symbol is illuminated to indi-cate that the instrument is in 'chart hold' mode.

Once replacement is complete, operate the Cancel (X) keythen use the 'Up arrow' key to access the zero and span set-ting keys. These allow the position of the new pens / print-head to be aligned with the 0% and 100% grid lines on thechart.

2.3.1 Continuous-trace recorders

Once the pens have fanned, open the recorder door and thedisplay unit (both hinged at their left edge) and pull each ofthe exhausted pens forwards off its guide bar.

Fit the new pens, by pushing them carefully onto the guidebar

2.3.2 Multipoint recorders

Once the printhead has parked, open the recorder doorand the display unit (both hinged at their left edge).

Remove the cassette (section 2.4) and pull the ex-hausted print cartridge vertically downwards out of itsholder.

Offer up the new cartridge to the printhead, and push itupwards into place.

Return the cassette to the chassis and close the displayunit and the recorder door.

2.4 CHART REPLACEMENT

Note:For recorders with status levels K13 or higher, if thecassette type (i.e. roll or z-fold) is changed, or if therecorder loses its configuration, the recorder must bereconfigured for the correct cassette type (Instru-ment configuration) or the chart drive will not oper-ate correctly.

Before changing the chart, carry out a pen park/fan asdescribed in section 2.3 above. Once the chart replace-ment is complete, carry out an alignment procedure asdescribed in sections 3.2.4 and 3.2.5, below.

2.4.1 Z-Fold charts

Remove the cassette, by pulling on the two latches asshown in the top figure. If a used chart is present, openthe take-up retainer and remove the used chart.

Open the top of the paper pay-out tray, and remove anyresidual paper dust. Open the chart guide.

Unpack the replacement chart and fan it several times toseparate the leaves and to remove as much perforationdust as possible.

Orient the chart so that the circular holes are to the left,the slots to the right, and the red end-of-chart line to theback (all directions relative to the front of the cassette).Place the chart into the pay-out tray, unfolding three orfour leaves at the same time. Pull the free end of thechart over the drive roller and down behind the chartguide and lay the free leaves in the take-up tray.

Ensure that the paper folds naturally into the tray, thatthe printed grid is uppermost and that the slots are at theright hand edge of the chart (i.e. the circular holes are tothe left).

Close the take-up retainer and the chart guide, ensuringthe paper holes/slots fit over the sprockets on the driveroller. Close the top of the paper pay-out tray, ensuringthat the chart is contained behind the flanges on the top.

3 OPERATION AND CONFIGURATION

3.1 OPERATION

The four-character, blue display shows the process value (PV) of each channel in turn, with each channel remainingon display for 5 seconds. If 'Units' is selected 'yes' in 'Units configuration', the channel display units alternate with thePV at the display. Current channel number is indicated by a green numeric character to the left of the PV display. Redarrow heads to the right of the PV display indicate which (if either) of the displayed channel's alarms is active, andwhether the alarm is configured absolute high (up arrow) or absolute low (down arrow).

Operation of either the Enter or the Cancel key allows entry to the recorder's configuration menus, via a password.The password is set to 010 at the factory, but can be edited in 'Instrument Configuration' (section 3.2.11).

Notes:1. Channels configured as 'Off' do not appear in the scroll sequence. If all channels are off, then channel 1 is shown

'Off' continuously.2. Unit string characters k, w and x cannot be displayed by a seven-segment display and are replaced by the special

symbol ' '. Similarly, the letter 'm' is displayed as 'n.n'. Because 'n.n' takes two character spaces, if an 'm' is usedin a unit string, the right-most character of four-character strings is lost. The above applies only to the display - thecharacters are printed correctly on the chart.

3. If the actual input value exceeds the configured range, +999.9 is displayed for over range; -999.9 for under range.

3.1.1 Channel Hold

Operation of the cursor key causes the currently displayed channel's value to remain permanently on display (Channelhold). Channel hold is indicated by a red 'H' below the channel number. (This red 'H' symbol is also used to displaychart hold (pen park) mode.) To return to normal scroll mode, the cursor key is operated a second time.

3.1.2 Channel scroll (Manual)

The channels can be scrolled through in both normal and channel hold mode by operation of the scroll up/down keys.In manual scroll all fitted channels are displayed when called, even if they are configured to be 'Off'.

3.1.3 Units display

See section 4.4.1 instead, if the 'Channel Tags' option is fitted.

If 'Units' have been selected 'yes' in the top level configuration menu, then the PV and Units displays alternate, withthe PV being displayed for three and a half seconds, then the units string for a second and a half. See note 2 above forun-displayable characters.

3.1.4 dFlt display

If the recorder's configuration should be found to be corrupt at power-up, a default configuration is loaded instead and'dFlt' is displayed, as a warning to the user, until either the Cancel or Enter key is operated.

figuration - section 3.2.6ddd-ddd A 20 character descriptor editable in 'Instrument configuration'. Initially set to 'Instrument'

CYCLIC MESSAGES

Note: If the 'Channel Tags' option is fitted see section4.4.2 instead.

Cyclic messages are printed on the chart approxi-mately every 2 cm. on a convenient time boundary.The messages are right-justified on the chart and areprinted in the following order:

Time; Date; Chart speed; Channel 1 tag, units andscale; Time; Date; Chart speed; Channel 2 tag, unitsand scale; ...and so on. Channel information isprinted on two lines, with Channel tag and scale 'zero'value at the left of the chart and units and span valueat the right of the chart, as illustrated in figure 3.1.6

ALARM ON/OFF MESSAGESHH:MM:SS ALARM ON(OFF) C:A

If so configured in the Instrument configuration (section 3.2.11), these messages, printed in black, appear when analarm becomes active or ceases to be active, and consist of the following elements:

HH:MM:SS Alarm on(off) timeALARM ON Specifies that the alarm became active at the above timeALARM OFF Specifies that the alarm ceased to be active at the above timeC Channel numberA Alarm number

Notes1. Alarm messages are printed in preference to cyclic messages, should they occur simultaneously.2. Alarm messages are inhibited when the Event Input option is fitted (section 4.3).

Display changes to FAn or PArc according to model

The rest of the Configuration menu (fig 3.2.1) is accessed using up/down arrow keys.

OPERATOR ACCESS LEVEL

Initially set to '0', this 'access level' requires the user to enter a password direct from the background display as de-scribed above. Once entered, the user has full access to the recorder's configuration. See section 3.2.11 (PASS) fordetails of password editing.

Setting the access level to 1 or 2 (AcES - Instrument configuration - section 3.2.11) allows the operator to carry outthe operations shown in table 3.2 without needing to enter the password.

Table 3.2 Operator access levelsENTER INDICATOR

Whenever a change is made to a configurable item, an E symbol appears in the channel number display. Operation ofthe Cancel (X) key resores the previous value and extinguishes the E. Operation of the Enter key, saves the new valueto the recorder's data base, and the E symbol disappears in three stages, as depicted below whilst the save takes place.

3.2 CONFIGURATION (Cont.)

NUMERIC ENTRY

There are two types of numeric field which can be identified - thosewhich display one of a fixed number of choices which are scrolledthrough using the up/down arrow keys (e.g. chart speed), and thosewhich have to be entered character by character. Scrollable fields canbe recognised because all the displayed characters flash together,whereas character-by-character items flash only the currently editablecharacter.

For the latter type, numbers greater than 9.999 (e.g. alarm thresholds)are entered as described in the following example, which shows how toenter a value of '123.4'. Because this document cannot easily show aflashing character the currently editable character is shown underlined.

Notes:1. The flashing 'H' character indicates that the – sign is the editable

character, and this – sign can be toggled on and off using the up/down arrow keys.

2. The units character is entered first (after the +/- sign), then the deci-mal point position.

3. To move the decimal point to the 10s or 100s position, the cursorkey is operateda) when the editable character is the least significant (right-most)digit (LSD), ANDb) this LSD is 0.Operating the cursor with anything other than zero as the LSD failsto shift the decimal point position.

4. Unless the display format is already 0.000, setting the most signifi-cant character to zero, then operating the cursor key, moves thedecimal point position left. For example, if you were to reset thevalue from 123.4 to 23.4, the display would change from 023.4 to23.40 when the cursor key was operated.

3.2.1 Configurable items

Figure 3.2.1 shows the order in which configurable items appear in what is called 'the top level configuration menu'.The figure shows the 'up arrow' order. Use of the down arrow reverses the order. Use of the Enter key takes the userdown to the next level of menu - the Cancel key takes the user back up one menu level each time it is used.

3.2.1 CONFIGURABLE ITEMS (Cont.)

CHARACTER SET

The printable character set is A to Z, 0 to 9, hyphen, space, degrees, underscore. The displayable characters are limitedby the nature of a seven-segment display; characters which cannot be displayed, even approximately (k, m, w, x), arereplaced by the special symbol ' '.

In scroll lists, mV for example is displayed as 'n.nU', and a type K thermocouple is displayed as 'Ca'.

3.2.2 Pen Park/Fan

As described in section 2.3, this is used to disable the chart and pen drives of the recorder so that the chart and pensor print cartridge can be changed safely. In the case of the continuous trace recorder, the pens 'fan' to allow easy ac-cess to them all.

3.2.3 Chart speed

Entry from the SPd display allows the chart speed to be chosen from a scroll list, using the scroll up and/or scrolldown keys. The chart speeds available are:

MULTIPOINT RECORDERSOff, 5 mm/hr, 10mm/hr, 20mm/hr, 30mm/hr, 60mm/hr, 120 mm/hr

CONTINUOUS-TRACE RECORDERSOff, 5 mm/hr, 10mm/hr, 20mm/hr, 30mm/hr, 60mm/hr, 120 mm/hr, 240mm/hr, 300 mm/hr, 600mm/hr, 1200mm/hr,3600mm/hr, 18m/hr (18n.n), 36m/hr (36n.n). If the annotator option is fitted, it will print only up to and including300mm/hr chart speed

3.2.4 Zero

This is used to align the traces to chart zero.

MULTIPOINT RECORDERSUpon entry, the chart advances, and a trace is placed on the chart where the recorder thinks chart zero is. The up anddown arrow keys are used to adjust the position of the trace so that it is aligned with the chart zero grid line.

CONTINUOUS-TRACE RECORDERSUpon entry, the up/down scroll keys are used to select a channel (default = channel 1). Use of the Enter key causesall pens but that associated with the selected channel to move to the centre of chart, whilst the selected pen moves towhere it believes chart zero is. The up and down scroll keys are used to align this pen's trace to the chart zero gridline. Operation of the Enter key confirms the new zero position.

To align another pen, use the cancel (x) key to return to the channel select page, use the up/down scroll keys to selectanother channel (annotator = A), and repeat the above process. Once all the required channel pens have been zeroed,two operations of the cancel key take the user back to the main menu.

3.2.5 Span

This is used to align the traces with chart full scale, and operates in exactly the same way as described above for chartzero, except, of course, that the alignment is carried out to the 100% chart grid line, not the 0% grid line.

3.2.6 Time and date setting

Note: This section applies to continuous-trace recorders only if they are fitted with the annotation option.

Figure 3.2.6 shows the key strokes necessary to set the time and date (in this example to 10 minutes to 4 o'clock pmon the 1st May 1998), and how to set the date format to European (Eu) which is Day/Month Year, or American (USA)which is Month/Day/Year. The clock re-starts at each operation of the Enter key, although it is not printed on thechart until the recorder is returned to its 'on-line' status using the Cancel (X) key.

Figure 3.2.6 Time and date setting

3.2.7 ADJ

The adjust section allows the recorder's input circuits to be adjusted to make allowance for non-standard inputs. Ifboth zero and span are adjusted, a dual point gain and offset adjustment will be applied. If only zero or only span isadjusted, then a single point offset adjustment will be carried out.

Note: If the hardware capabilities are exceeded, or if the input is in ERROR, or if the input has been configured withan invalid range, the displayed value is ---- and in such cases the adjustment is ignored.

ZEroAfter selecting the required channel for adjustment, operate the Enter key whilst 'ZERO' is displayed. Apply a knowninput, as close to the required zero point as possible. Use the cursor and up/down arrow keys to set the displayedvalue to the known input value. A further operation of the Enter key confirms the change.

SPAnThis operates in the same way as described for 'ZERO' above, except the known input should be as near to the re-quired span value as possible.

CLrOperation of the Enter key whilst CLr is displayed calls a confirmation menu in which the up or down arrow is usedto select 'yes' or 'no'. Operation of the Enter key with 'yes' selected causes any adjustments previously made to therelevant channel to be removed.

3.2.8 Alarm set up

This allows an alarm threshold to be set, and the alarm type to be defined as absolute high or absolute low. The defaultthreshold setting is 0.000 and this can be edited using the up and down arrow keys and cursor as described in section3.2 above.

Figure 3.2.8 shows the keystrokes necessary to set the threshold of Channel 2, alarm 1, and how to define it as abso-lute low.

An alarm can be disabled only by setting its threshold outside the range of the input signal.

See also CREL (section 3.2.11) for details of how to use the relay associated with channel 1 alarm 1 as a global alarmindicator and HySt (section 3.2.11) for how to set a hysteresis value for all alarms. (See glossary for a description ofhysteresis.)

3.2.9 Range

Note: See section 4.4.3 instead, if the 'Channel tags' option is fitted.

This section allows the configuration of the input channels to be entered. Figure 3.2.9 shows the top level range con-figuration menu for three cases:1. Input type = thermocouple or RTD; Linearisation = TC or RTD type.2. Input type = V, mV, mA or ohms; Linearisation type = linear or square root and3. Input type = V, mV, mA or ohms; Linearisation function = Thermocouple or RTD type.This last combination is used with transducer transmitters which do not incorporate their own linearisation tables.

Notes:1. Channel one must not be used whilst configured as 'Ohm' or 'RTD' unless the CJ sensor has been disconnected

(figure 2.2), or gross measurement errors will occur. When the CJ sensor disconnected, no other input channelshould be configured as T/C unless it uses an external CJC.

2. The background (PV) display will show 'brng' (bad range) if any one or more of the following obtain:a. Input range low ≥ Input range highb. Linearisation range low ≥ Linearisation range highc. Scale low = Scale highd. Hardware capabilities are exceedede. Linearisation type is inappropriate to the rest of the configuration

3.2.9 RANGE (Cont.)type

Scrollable through Off, tc (thermocouple), mV, Volts, mA, RTD, Ohm. If Off, then none of the headings below ap-pears. Where different input types are to be used, resistive inputs (RTD or potentiometer) should not be connected tochannel 1. If channel 1 input must be resistive, the cold junction sensor must be disconnected as shown in figure 2.2above, and any thermocouple inputs must then use external cold junction compensation.

Lo/HiThese two input range entries represent the lowest and highest values the input is likely to have placed across it, inengineering units. (E.G. For a thermocouple, the input range would be in ˚C or ˚F.)

LINThis allows a linearisation function to be chosen for the input. The scrollable list consists of the following where theactual displayed item appears in parentheses (), if it is affected substantially by the constraints of the display:Thermocouples type: B, C, D, E, G2 ( 2), J, K (CA), L, N, R, S, T, U, NiNiMo (nini), Platinel (Plt).Resistance thermometers type: Pt100DIN (P100), Pt100ANSII (P10A), JPt100 (JP10), Pt1000 (1000),

Ni100 (N100), Ni120 (N120)Other linearisations: Linear, Square root.

UNITFor thermocouple or RTD types, the units string can be scrolled between ˚C and ˚F as required. For other types, afour character units string can be entered, using the text entry techniques described in section 3.2.1 (Character set).

SCLo/SCHiFor mV, mA and Volt input types only, this allows a scale low and scale high value to be entered. For example, a volt-age input of 0 to 5 Volts (input range) may be required to be displayed, for example, as 0% (Scale low) to 100%(Scale high), or 1000 to 5000 RPM and so on.

Lo/HiWhere this appears after the LIN menu item, these entries cater for the case where a remote transducer is attached to anon-linearising transmitter. In these circumstances a signal of, say, 4 to 20 mA (input range) might be equivalent to400 to 1600 ˚C (linearisation range). It is this linearisation range which is entered here.

CJCThis field appears only when 'type' = tc, and' Lin' is a thermocouple type, and allows the user to use no cold junctioncompensation (CJC) (none), the internal CJC supplied by the recorder (int), or an external cold junction held at aknown temperature (Etn). Where external is selected, the following item is 'EJC', which allows the temperature of theexternal CJC to be entered.

EJCAllows the temperature of an external cold junction to be entered. See CJC immediately above for more details. ThisEJC item appears only when CJC has been selected as external (Etn).

SHUNAllows a shunt value to be entered for mA type inputs.

RESPAllows the user to select none, Drive High (drhi) or Drive Low (Drlo) as the recorder's response to an open circuit(R>10MΩ) at its input. Where 'none' is selected, the channel drifts according to the induced voltages in the signalwiring. When selected high (low) the channel will be traced at >100% (<0%) on the chart.

DECPAllows the user to determine the position of the decimal point at the recorder display. The positions can be scrolledthrough, from 0.000 through 00.00 and 000.0 to 0000.

3.2.10 UNIT

This allows the user to choose whether or not to display the channel units or not. If 'No' is selected, the backgrounddisplay carries out its normal 5-second scroll through the channels as described in section 3.1 above. If 'Yes' is se-lected, then the normal 5-second scroll continues, but each channel's units are displayed for about a second and a halfjust before the next channel's PV appears. See Note 2 in Section 3.1 regarding non-displayable characters.

3.2.11 INST

This section of the configuration allows the Password to be edited, the 'Common Relay' function to be enabled/disa-bled, the chart cassette type to be defined (roll or z-fold (fanfold)), Alarm Hysteresis to be set, Alarm messages to beenabled or disabled, an instrument descriptor to be entered and the operator access level to be defined.

Figure 3.2.11 Instrument configuration menu.

PASSAllows a new password to be set for entry to the configuration menus. If set to '000', no password is required for sub-sequent entry to configuration. See also 'Operator access' in section 3.2 above, and ACES below.

CRELCommon Relay enable. When set to 'On', Channel 1 Alarm 1 relay operates if any channel's alarm becomes active.When set to 'Off', the relay operates only when channel 1 alarm 1 becomes active.

DESCAllows a 20-character text string (descriptor) to be entered using the cursor and up and down arrows to enter eachcharacter in turn. When the cursor is operated from the 20th character position, it returns to the 1st character position.To indicate that this has happened, character 1 of the decriptor is always preceded by a special character ( ). Forexample, were the descriptor ' DOWNLINE TEMPERATURE' to be entered, (where the highlighted text indicates thefour characters on display) and the cursor operated from the final E, the display would change to : " DO NLINE

TEMPERATURE'.

As indicated above, characters which cannot be displayed (K, M, W, X) are represented by another special character( ). (These non-displayable characters do print correctly on the chart). See section 3.1 above for the full characterset available.

HyStAllows a hysteresis value (as a percentage of channel scale) to be entered for all the alarms' thresholds, as a percent-age of Channel scale. See the Glossary of terms for a description of hysteresis.

n.nESAllows the printing of alarm messages to be enabled/disabled. When enabled, the messages:

HH:MM:SS ALARM ON C:A, and HH:MM:SS ALARM OFF C:Awill be printed on the chart, in black, at the appropriate time.HH:MM:SS is the time of occurenceC is the relevant channel numberA is the relevant alarm number

Note: If the 'Event input' option is fitted, the printing of alarm messages is inhibited.

ACESAllows operator access to be set to level 0, 1 or 2 as required. See 'Operator Access' in section 3.2 for further details.

CASSThe recorder is set up at the factory to suit the type of cassette fitted. Should the cassette type be changed (from roll toz-fold (fan fold) or vice versa), then this 'CASS' field needs to be accessed, and the new cassette type selected usingthe up/down arrow keys. If this is not done, the chart drive will become extremely noisy, or the chart time accuracywill be lost, according to type.

4 OPTIONS

Up to four 1/2-width option boards can be fitted, as specified at time of order (i.e. options are not retro-fittable).

4.1 RELAY OUTPUTS

The relay output option comes in three versions, each of which uses a 1/2 - width circuit board. The relay specifica-tion for resistive loads is as given below. For inductive ac loads, contact life = resistive life x reduction factor in figure4.1a, in which F1 = measured on representative samples; F2 = typical values (according to experience)

Maximum ac switching power 500 VA

Maximum ac contact voltage 250V within the VA rating above

Maximum ac breaking current 2 A, within the VA rating above.

Maximum dc power/voltage/current See figure 4.1b.

Isolation (dc to 65Hz; BS EN61010) Installation category II; Pollution

degree 2 (See specification section

for definitions)

Contact to contact 300V RMS or dc (double insulation)

Contact to ground 300V RMS or dc (basic insulation)

Estimated life 30,000,000 operations

Each recorder channel has two alarm thresholds (alarm 1 and alarm 2),which can both be either absolute high or abso-lute low as defined at time of order. If the channel's value lies above a high threshold, the relevant relay for thatchannel alarm is active. If the channel's value lies below a low threshold, the relevant relay for that channel alarm isactivated.

Notes:1. The default hysteresis value of 1% can be edited as a part of the instrument configuration (HySt). This value is a

percentage of channel scale, and applies to all thresholds.2. The relays are de-energised in alarm and power off conditions, to provide fail-safe operation.

4.1.1 Three change-over relays board

This 1/2 board provides three change-over relays (i.e. with common, normally open and normally closed contacts).In alarm, the common and normally closed contacts are closed. Wiring details for up to 12 relays is shown in figure4.1.1.

4.2 TRANSMITTER POWER SUPPLY OPTION

4.2.1 Introduction

This option supplies one or two sets of three iso-lated 25 Volt outputs wired to terminal blocks foruser connection. Each output is intended to sup-ply power to a remote transmitter in order to run a0 to 20 mA or a 4 to 20 mA current loop.

Figure 4.2.1 shows an overall view of a transmitterpower supply option fitted in the rear terminalcover.

FUSES

The fuse is a 63mA (220/240V) or 100mA (110/120V), 20mm anti-surge type T located on thecircuit board as shown in figure 4.2.1 above.Spare fuses are available from the manufacturer.

SAFETY ISOLATION

Isolation (dc to 65Hz; BS EN61010) InstaIlation category II; Pollution degree 2 (see section 6 for definitions)

Channel to channel = 100V RMS or dc (double insulation); Channel to ground = 300V RMS or dc (basic insulation)

4.2.2 Signal wiring

Each set of outputs is terminated at a terminal blockas shown in figure 4.2.2

In order to read input values successfully a resistormust be connected across V+ and V- of the inputchannel. This resistor should have a minimumspecification of 1.4 Watt, ±1% and should be either100Ω or 250Ω in value as required. Resistors of thiskind are available from the manufacturer.

4.3 EVENT INPUT OPTION

This option offers four inputs to control chart on/off and annotation of events. Each event is initiated by a contactclosure (or opening) applied between the 'C' terminal and input terminals one to four.

Note: Alarm message printing is inhibited if the Event Input Option is fitted.

4.3.1 Contact input 1

With the contact closed, the chart runs normally, at its selected chart speed.

When the contact is opened, pens are parked at zero (continuous-trace recorders) or tracing is stopped (multipointrecorders), the chart winds forward eighty mm. and stops.

Contact input 1 may not be closed if contact input 2 (below) is closed.

4.3.2 Contact input 2

This function applies only to annotating recorders.

At closure, the current time and date is printed on the chart. For as long as the contact is closed, the chart runs at itsselected speed, but annotation of scales, time, date and chart speed is inhibited.

At contact opening, pens are zeroed (contiuous-trace recorders) or tracing is inhibited (multipoint recorders), time,date, scales and chart speed are printed on the chart, the chart is wound forwards 80 mm. and is then stopped.

Contact input 2 may not be closed if contact input 1 is closed.

4.3.3 Contact input 3

This function applies only to annotating recorders, and is effective only if contact 1 or 2 is closed.

On closure, the message "EVENT START HH:MM:SS" is printed at the left-hand side of the chart, whereHH:MM:SS shows the time of closure in hours, minutes and seconds.

On contact opening, the message "DURATION HH:MM:SS" is printed at the left edge of the chart, whereHH:MM:SS shows how long the contact has been closed to the nearest second. Should the duration of closure reach100 hours, the duration re-sets to zero.

4.3.4 Contact input 4

If contact 1 or 2 is closed, then channel four (continuous trace) or channel six (multipoint recorders) is used to showthe status of contact closure 4. Whilst contact 4 is open, the trace is at 100% of chart span; whilst closed, the tracemoves to 96% of span.

If neither contact 1 or 2 is closed, pen four (continuous-trace recorders) moves to chart zero or tracing by channel 6(multi-point recorders) is stopped.

100 MM CHART RECORDER USER GUIDE

4.4 CHANNEL TAGS OPTION

This option allows the user to enter a text string (tag) describing the input channel. The string can be of up to fourcharacters in length, using the character set described in section 3.2.1. If the option is fitted, the following sub-sec-tions replace the referenced topics in section 3 in the manual.

4.4.1 Units display(Replaces section 3.1.3)

If 'Units' have been selected 'yes' in the top level configuration menu, then the PV and tag text strings alternate, withthe PV being displayed for three and a half seconds, then the tag for a second and a half.

Unit string characters k, w and x cannot be displayed by a seven-segment display and are replaced by the special sym-bol ' '. Similarly, the letter 'm' is displayed as 'n.n'. Because 'n.n' takes two character spaces, if an 'm' is used in a unitstring, the right-most character of four-character strings is lost. The above applies only to the display - the charactersare printed correctly on the chart.

4.4.2 Cyclic messages(Replaces 'Cyclic messages' in section 3.1.6)

Cyclic messages are printed on the chart approximately every 2 cm. on a convenient time boundary. The messagesare right-justified on the chart and are printed in the following order:

Time; Date; Chart speed; Channel 1 identifier (Ch1), tag and scale; Time; Date; Chart speed; Channel 2 identifier(Ch2), tag and scale; ...and so on. Channel information is printed on two lines, with Channel number and scale 'zero'value at the left of the chart and units (or tag) and span value at the right of the chart, as illustrated in figure 4.4.2

4.4.3 Range(Replaces section 3.2.9)

This section allows the configuration of the input channels to be entered. Figure 4.4.3 shows the top level range con-figuration menu for three cases:1. Input type = thermocouple or RTD; Linearisation = TC or RTD type.2. Input type = V, mV, mA or ohms; Linearisation type = linear or square root and3. Input type = V, mV, mA or ohms; Linearisation function = Thermocouple or RTD type.This last combination is used with transducer transmitters which do not incorporate their own linearisation tables.

Notes:1. Channel one must not be used whilst configured as 'Ohm' or 'RTD' unless the CJ sensor has been disconnected

(figure 2.2), or gross measurement errors will occur. When the CJ sensor disconnected, no other input channelshould be configured as T/C unless it uses an external CJC.

2. The background (PV) display will show 'brng' (bad range) if any one or more of the following obtain:a. Input range low ≥ Input range highb. Linearisation range low ≥ Linearisation range highc. Scale low = Scale highd. Hardware capabilities are exceedede. Linearisation type is inappropriate to the rest of the configuration

Alarm A function which is triggered when an input signal or a signal derived from it reaches a cer-tain value. Once triggered, the alarm can cause a relay output to change state.

Analogue input An input which changes in a smooth (non-stepped) way (e.g. thermocouples, resistance ther-mometers).

Attenuator A resistive device which reduces the signal voltage by a known ratio (usually 100:1)Break response The recorder can detect an open circuit at its input terminals and, the instrument’s response

to an open circuit can be defined as ‘None’, ‘Drive high’ or ‘Drive low’. If none’ is selectedthe trace is allowed to drift according to what the input wiring is picking up (acting as anaerial). Drive high (low) causes the trace to be drawn at the extreme right (left) side of thechart.

Chart cassette A mechanical paper transport system for containing and feeding the chart past the pens orprinthead at a known speed. The cassette includes reservoirs for unused (pay-out tray) andused (take-up tray) sections of chart.

Cold Junction Compensation Also known by the abbreviation CJC. The voltage generated by a thermocouple (TC) junc-tion depends on the temperature difference between the actual bonded junction (the hot junc-tion), and the other (non-bonded) end of the conductors (the cold junction (CJ)). Thus, forany reading from a TC to be accurate, the temperature of the CJ must be taken into account.This can be done in three ways: Internal, External or Remote.Internal. The recorder has integral temperature detectors measuring the temperature near theterminal blocks (the cold junction for directly connected TCs).External. For remote TCs, the cold junction can be held at a known temperature. This tem-perature is entered (in degrees) as a part of the CJC configuration.Remote. For remote TCs, an auxiliary temperature detector can be used to measure the coldjunction temperature. This detector is then connected to a separate input channel. This inputchannel number is entered as a part of the CJC configuration.

Configuration This is used as a verb to mean ‘the process of telling your recorder what you want it to do’,and as a noun to mean ‘the way in which the recorder has been set up (or configured)’.

Continuous trace This is used to describe recorders which have a single pen associated with each processvariable, and this pen traces the value continuously. See also multipoint recorder.

Digital (discrete) input An input which has only two states (on or off). Examples are switch inputs or voltage pulseinputs.

Event input A discrete (switch) or digital (voltage level) input.Hysteresis When an input signal is ‘hovering’ near a setpoint, then an annoying and potentially damag-

ing series of alarms can be generated, instead of just one alarm the cause of which can bedealt with if necessary. To avoid this, a ‘hysteresis’ value of 1% span is applied, whicheffectively puts a dead band round the set point. For example with a span of 0 to 1000 anabsolute high alarm with a set point of 100 will have a hysteresis value of 10. The alarm istriggered when the input signal value rises above 100, but will not re-trigger until after thealarm has been ‘cleared’ by the process value falling below 90. An attempt to depict thisexample is given in the figure below.

Input channel An input circuit which accepts voltage, current or digital input signals from the user.Input signal A voltage, current or digital input applied to the recorder input circuits. See also Analogue

input and Digital (discrete) input.

7. GLOSSARY OF TERMS (Cont.)

Linearisation table Most transducers produce an output which is not directly proportional to the input. Forexample, the voltage output from a thermocouple does not vary linearly with the tempera-ture it is exposed to. The recorder uses a ‘look-up’ table to find a temperature value for anymV input from a specified thermocouple type. Similar tables exist for other transducerssuch as resistance thermometers.

Measured value An umbrella term which means: the value of an input channel, derived channel, totaliser,counter, timer etc. measured in mathematical units as a proportion of the span. See alsoProcess variable.

Multipoint recorder This is used to describe recorders which have multiple pen printheads rather than individualpens to produce the trace on the chart. Each trace is made up of dots, produced by the print-head as it traverses across the chart at regular intervals. Advantages are that many moretraces can be laid down on the chart, the traces can be annotated for identification and mes-sages can be printed on the chart. Disadvantages are that fast transients may be missed atlow chart speeds.

Operator interface A term used to describe the controls (e.g. pushbuttons, keypads) that are used to operate andconfigure the unit.

Paper transport system This includes the chart cassette and the mechanical system, motors etc. needed to move thechart through the cassette. The paper transport system is often considered to be an integralpart of the writing system.

Pen A fibre-tipped disposable stylus with an integral ink reservoir. Used to draw (trace) thevalue of a single process variable on the chart in continuous trace recorders.

Pen tray With modular recorder designs, each pen has its own mechanical system (including motorand feedback device) associated with it to drive it backwards and forwards across the chart.Pen tray is the general term for such mechanical systems. With some recorders, the pendrive electronics are integral with the pen tray.

Printhead This is a device which, together with a disposable multi-colour cartridge, allows multi-pointrecorders to mark the chart.

Process variable An umbrella term which means: the value of an input channel, derived channel, totaliser,counter, timer etc. measured in engineering units (e.g. Degrees Celsius). See also Measuredvalue.

Relay output A set of contacts which changes state as a result of an alarm becoming active. Relays areenergised continuously except when ‘in alarm’, so that if power to the recorder fails they gointo their ‘alarm’ state.

Resistance thermometer Also known as a resistance temperature detector (RTD), a resistance thermometer is con-structed of a material whose resistance varies in a known way with the temperature it is ex-posed to. The resistance variation is non-linear, but for any given type, this non-linearity iswell known and invariable and is compensated for by linearisation tables in the recordermemory.

Setpoint Also known as ‘threshold’, this is the point at which an alarm becomes active or inactive.See also hysteresis.

Shunt The input circuit of each recorder channel measures voltage signals. If current signals areconnected to the recorder, a low value resistor must be placed across the inputs, to convertthe current signal to Volts, according to Ohms law (Volts = Amps x Ohms). Thus, a 0 to20 mA (0.02 Amps) signal applied across a 250 Ω resistor produces a voltage range of

0 to (0.02 x 250) Volts = 5 Volts.Such resistors are called ‘Shunt resistors’ or ‘Shunts’ for short, and are usually of very closetolerance.

Span Span has two common meanings: the right-most grid of the chart, or the value given by(maximum value - minimum value). The two meanings are identical where the minimumvalue is zero.

Trace The line produced on the chart or display screen showing the value of the process variablebeing measured.

Thermocouple A junction of two dissimilar metals which produces a small voltage, the value of which de-pends on the temperature of the junction. The voltage varies in a non-linear way with tem-perature, but for any given type, this non-linearity is well known and invariable and iscompensated for by linearisation tables in the recorder memory.

Threshold See setpoint.Transducer A device which produces an electrical output proportional to temperature, flow rate, pres-

sure, speed, position etc. Common transducers are potentiometers, thermocouples, resistancethermometers (RTDs) and flow meters.

Transmitter Thermocouple wire (compensation wire) is expensive, and if the thermocouple is a longway from the measuring device, it is often cheaper to instal a ‘transmitter’ local to the ther-mocouple. This device converts the mV signal from the thermocouple to a mA signal whichcan then be wired to the recorder using normal copper wire. Transmitters can be self pow-ered, or they may need power generated for them. Most recorders can be fitted with Trans-mitter Power Supplies as an option.

Writing system A general term used to describe the mechanical means of moving pens/printheads across thechart width. The term often includes the paper transport system used to drive the chartthrough the cassette.

Zero Zero is generally taken to mean the value associated with the left-most grid line on the chart.Its actual value need not be zero, as long as it is less than the Span value.
